Astaria will be a class based MMORPG. In order to promote teamplay, they will follow the Holy Trinity (Tank, Healer, DPS). Players will pick one of six base classes: the Squire, Swashbuckler, Archer, Acolyte, Chemist and Adept. These classes are Tier 1 classes. After players reach a certain point within that class, they may advance to Tier 2 classes by finding the questline to do so. These class changes will have conditions and stat checks to find out if the player is ready to undergo advancement. Players who are Tier 2 classes can swap out abilities from the new class while retaining all previous Tier 1 abiltiies. Advancing classes allows flexiblity and choice. Tier 3 classes will also be available after release. Class advancements do not provide immense power gains but do provide a different playstyle or flexibility.
